| Abstract: | This paper use an accident of 220 kV XLPE cables’ water penetration to analyze the cause and harm in construction and running of HV XLPE cables in our country.We make our points in drying cables with water penetration.Then we compare water content standard of SF6 with transformers and GIS switches in different conditions.It is preliminary to be made certain the goal of water content after water penetration cables is dried.Then we compare the result of water penetration cables and non-water penetration cables,and we can make sure of the standard in drying water penetration cables.It provides the basis of handling water penetration problems in HV XLPE cables. |
